Sanders spokesman Michael Briggs told the AP that the candidate had been told of Oliver’s passing and the campaign planned to issue a statement.

“It’s very sad,” Briggs said.

The baby’s mother took to social media to express her sorrow, writing on Facebook: “I love you dearly, I love you most. I love you with all my heart and soul. I know that God will keep you near since God and truth are here.”

Funeral services are scheduled for 12:30 p.m. Tuesday at Forest Lawn Hollywood Hills Church of the Hills.
